Oregon wing Teondre Williams will miss his second straight game as he is not going through warm-ups in preparation for Sunday's game against Portland State.

Williams, who fell hard in the Texas Southern game, played against Duke then missed the Missouri game because of headaches. Coach Dana Altman had said Thursday that Williams would be undergoing further medical tests. Dressed in warm-ups, Williams was only watching as the Ducks underwent pregame drills.

Jacob did not play in the Missouri game because of soreness in his right knee, on which he had arthroscopic surgery in late October.
